Description
The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.
Form
Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant mature human CD32b consists of 183 amino acids after proteolytic removal of the signal peptide and predicts a molecular mass of 20.8 kDa. By SDS-PAGE under reducing conditions, it migrates as an approximately 25-30 kDa protein due to glycosylation.
